Bond Angles

[Kaleb Tesfaye 1I]

Does the type of chemical bond (single, double or triple) affect the bond angle of a molecule?

I don't know the in-depth answer, but yes.
This website does a good job explaining it.

I also looked up some information on the correlation of amount of bounds and the bond angles, so I also know that bond angles are affected by the number of bonds. However, I don't think that this is something we need to focus on too much because the syllabus does not necessarily mention this concept.

I also was looking up more information and I found that bond angles are affected the three factors: state of hybridization of central atom, lone pair repulsion, and electronegativity. Lone pair of electrons at the central atom always try to repel the shared pair of electrons, thus, bonds are slightly displaced and result in a decrease of bond angle. In addition, if the electronegativity of the central atom decreases, the bond angle decreases.

I believe that this is not the central focus of bond angles that Dr. Lavelle wants us to get out. A huge part of bond angles is the number of bonding pairs compared to the lone pairs of the molecule as the lone pairs have greater repulsive forces than bonding pairs and thus cause one of the most substantial differences in bond angles. I would focus on the orientation of the total bonds around the central atom more so than the number of bonds between individual elements (single, double, or triple).
